B4J Question Confused with the use of libraries

[Stuart Moors]

While new to B4X, I'm certainly no newbie programmer, but I'm having difficulty understanding how the library system works (with B4J to begin with, but B4A later)

I've been looking for some string manipulation functions, so I selected jStringFunctions in the Library Manager and performed a refresh, but there is no change to the Intellisense list of available methods or properties. How should I (for instance) get to find a Right() function offered as a valid construct?
Am i missing something fundamental here?

Am i missing something fundamental here?

The object definition of JStringFunctions?

dim fnc As JStringFunctions
fnc.[Method here]

Don't use JStringFunctions. It is not needed and unmaintained for many years.

Dim s As String = "abcdefgh"
Dim Last4Chars As String = s.Substring(s.Length - 4)
Log(Last4Chars)

Thank you both for your prompt answers
So the bigger question, then is, without reading the associated XML, is there any way of discovering what functions/methods are implemented in a given library?

The IDE will show the list of types and the list of methods and events.

You can use this tool: https://www.b4x.com/android/forum/threads/b4x-help-viewer.46969/#content or this one: http://www.b4x.com/android/forum/threads/help-documentation-b4a-object-browser.25682/

The documentation for most libraries is available online (though it is not always up to date): https://www.b4x.com/b4j/help/jstringfunctions.html
You can find it by searching for the library name with the product filter:
